Frankly , I had never thought much about this. but thanks to google I now know it is:

ADDRESS UNKNOWN
The Ink Spots
Written by: Vaughn Horton/Denver Darling/Gene Autry

- #1 week of November 11, 1939

Address Unknown - not even a trace of you.
Oh what I'd give to see the face of you.
I was a fool to stay away from you so long.
I should have known there'd come a day when you'd be gone.

Address Unknown - oh how could I be so blind?
Who'd think that you would never be hard to find?
>From the place of your birth to the ends of the earth
I've searched only to find - only to find - Address Unknown.

(Spoken:)
Address Unknown - honey chile, I ain't even got a trace of ya.
You know one thing?
I'd give anything in the world just to see the face of ya.
I was a fool to stay away from you and everything else so long.
I should have been diplomatic and figured that some day
You'd be solid gone.

Address Unknown - oh how could I be so blind?
Who'd think that you would never be hard to find?
>From the place of your birth to the ends of the earth
I've searched only to find - only to find - Address Unknown.

Truly, I don't remember ever hearing this song an any radio show that specializes in songs of the 1930s and '40s. But I solid dig the Ink Spots. And B-Cowboy star Gene Autry, one of my boyhood heeroes, is listed as one of the writers. That makes it extra special.
